Title: Non-woven fabric based on synthetic fibres
IPC: D04H1/60
Filed: 1965-09-21
Abstract: 1,124,481. Non-woven fabrics; treating apparatus; pile fabrics. LUDLOW CORP. 21 Sept.. 1965 [21 Sept., 1964; 25 June, 19651, No. 40225/65. Headings D1K, D1L and DIR. A porous non-woven web has at least 25 % by weight of its fibres of a thermoplastic polymer, the fibres are randomly bonded by discrete particles of a fused synthetic thermoresponsive resin. ("Synthetic thermoresponsive resin" includes not only conventional synthetic thermoplastic polymers but also synthetic resins that are not truly thermoplastic, e.g. cross-linked polyvinyl chlorides.) The thermoplastic fibres on one surface have been partly heat-fused independently of the binder to make that surface smoother and denser than the other. As shown, a non-woven web is formed at I by carding, garnetting with crosslaying, needling, or air-laying, calendered between two rollers 3 and 4 of which the lower only is heated, and passed to the endless belt 6. A hopper 8 contains powdered binder and releases it between feed roll 10 and doctor blades 9 onto a vibrating screen 11 which distributes it over the web. Distribution is also helped by a current of air drawn through the web by a vacuum bar 12. The web then passes through an oven 17 where it is heated, e.g. by hot air to a temperature high enough to fuse the binder but not the thermoplastic fibres. The web is immediately pressed between cool rollers 18 and 19 and rolled up at 20. The thermoplastic fibres may be of polypropylene, regenerated or waste nylon, polyethylene, polybutene, polyisobutylene, or polyurethane. They may be flat, round, oval or square, and may be crimped. The web may also include another fibre, e.g. rayon cotton or ethylene-vinyl acetate copolymer fibre. The binder may be polyethylene, polyvinyl chloride, or ethylene-vinyl acetate copolymer, may be blended with a pigment, e.g. carbon black or burnt umber, and may contain antioxidants, stabilizers, dyes, or agents to facilitate needling. In modifications, the web is passed over a vibrating plate or between cold calendering rolls instead of over the vacuum bar 12; or is pressed in a heated platen press or between endless belts instead of being heated in the oven 17. The product may be used as a backing for a tufted carped or flocked carpet.

Abstract: 1330820 Endless conveyers handling eggs A MICHELBACH 1 Sept 1972 [22 Nov 1971] 40622/72 Heading B8A Eggs conveyed on belts 4, 5, 6, on respective floors of a laying battery (not shown), are delivered to selected baskets 10-13 carried by conveyer chains 8, 9. Each basket comprises a U-shaped stirrup having arms 26, 27 (Fig. 3), the ends of which are rotatably mounted in apertures 18, 19, of chains 8, 9. The cross-member 22 of the stirrup is surrounded by a tube 23 which is slotted at 28, 29, at its ends so that it can extend laterally at each end beyond the arms 26, 27. The slots 28, 29, are sufficiently wide to enable the tube 23 to have 90 degrees of rotary lost motion relative to the stirrup cross-member 22 as indicated by the angle 62 (Fig. 1). Rake members 31-36 are welded to the tube 23, and the 90 degrees of movement provides at one limit a receiving position for eggs arriving from conveyer 4 (as shown by basket 10) and at the other limit, a delivery position (as shown by baskets 11-13) for feeding the eggs to a conveyer 51. An auxiliary chain 80 driven from the conveyer chain 8 by a sprocket 83, drives cranks 87, 88, and 89, mounted for rotation just upstream of each respective conveyer 4, 5, and 6. The cranks 87, 88, and 89, are positioned so as to engage an arm 30 rigid with the tube 23 of each basket 10-13. There are thirty baskets 10-13 in all, and each crank 87 is phased to engage the arm 30 of every third basket as it passes the delivery zone of conveyer 1, so as to tip up the basket into the receiving position (as shown in Fig. 1). The phasing of the crank 88 is such that every third basket minus one is deflected to the receiving position at conveyer 5, and similarly every third basket minus two is deflected at conveyer 6. In the receiving position the rake arms pick up an egg present on relatively staggered fixed arms downstream of the conveyer 4, 5, or 6. The egg rolls into a shaped receiving portion of the conveyer basket. The latter is then turned back into its delivery position (as shown at 11-13) by a further arm 73 of the basket, engaging a fixed pin 93, 94, or 95 (Fig. 1). The eggs are then discharged at 50 on to the conveyer 51.
